I had been planning on switching to Verizon because I have had a bad experience with AT&T this year (I went almost 8 years without a single problem from them...). I was so excited because Verizon finally had no shortcomings compared to AT&T then when I heard this I was like sh!t! I seriously reconsidered switching, but then I realized that I NEVER use data and phone at the same time. Only time I could ever think about is if someone called me while using turn by turn nav, but I have been on iOS 6 since June and have only had this happen once. Everyone I talk to knows to text me first to make sure I am available anyway.
